INSIDE IVIOLDING-NIACHINE.

SPECIFICATION forming part of Letters Patent No. 515,S13,dated February 20, 1894.

Application filed March 16, 1893.

To a/ZZ whom t may concern:

Be it known that I, JOHN H. BLAIsDELL, a citizen of the United States, residing at Worcester, in the county of "Worcester and State of Massachusetts, have invented a new and useful Improvement in Inside Molding- Machines, of which the following isa specification.

The aim of this inventionis to improve the arrangement of parts and construction of planing machines that are adapted to plane the upper and lower surfaces of the material, and to plane or finish the sides of the material, either at right angles to the horizontal surfaces, or at an incline thereto.

To this end the invention consists of the device described and claimed in this specification, and illustrated in the accompanying four sheets of drawings, in which- Figure 1 is aplan of my improved planing machine. Fig. 2 is a side elevation thereof. Fig. 3 is a sectional side elevation on the line 3--3 of Fig. 1, looking toward the rear of the Fig. 4 is an enlarged sectional view of one of the vertical cutters, showing the way that the same is mounted. Fig. 5 is a rear view of the parts shown in Fig. 4. Fig. 6 is an enlarged detail of one of the adjusting mechanisms used for the guides. Figs. 7 and 8 are details of the screws, and clamping mechanisms used to move t-he vertical cutters. Fig. 9 is an enlarged side view of one of the guide holders, and Figs. 10 andll are details thereof.

My invention, generally speaking, consists in improving the details and arrangements of parts used in a planing machine, whereby the material can be more easily handled, and more accurately planed and finished, and whereby the machine can be nicely adjusted and manipulated by the operator.

Referring now to the drawings, I will de.- scribe my invention in detail.

10 and 1l represent the usual side frames of the machine.

12 represents the feeding-in table, which is secured to the frames l0 and 11 by means of the supports 13, and upon this feeding-in table, the materialto be operated, is first placed. This feeding-in table has two slot-s let and 15, as shown, and into these slots are adapted to Serial No. 466,220. (No model.)

19 represents a pivot which is mounted on the table 12, and mounted on this pivot is a bell-crank 20, which carries at the end thereof, a long spring 21,'which is adapted to press against the material as the same is drawn into the machine, and to keep the same firmly against the guide 1S. .In the other end of the bell-crank 20, is pivoted the nut 22, which nut 22 has tapped into the same a screw 23, which has the handle 24 at the end of the machine, and which screw 23 is carried by a lug 25 projecting from the Atable 12.V Thus, it will be seen that this device forms, a neat, simple,

vand accurate guiding mechanism for guiding the material into the machine.

The guide 18 is'first properly set so that the material will fit between the same and the spring 2l, and then the spring 2l is adjusted by means of a handle 24, so that the beam or plank will be kept firmly against the guide, the spring or yieldofthe flexible piece 2l taking care of the inequalities in the rough' material. 1

The driving shaft 26, of the machine, is journaled in a box 27 mounted on the frame 10, and in a box 28 mounted on the frame 11, andvin an outside bearing 29, which may be secured to the iioor of the machine, as shown in Fig. 1. On this driving shaft 26 are mounted in the usual manner, the loose pulley 30 and the tight pulley 31, and a belt is run around these pulleys from anysuitable source of power, and by this means, power may be transmitted tothe machine. On the shaft 26 are also mounted two pulleys of equal size on opposite sides of the frames, as 32 and 33, and these pulleys constitu te the pulleys which actuate or drive the horizontal cutters, as hereinafter described. On the front end of the shaft 26 is mounted the feed pulley 34, and from this feed pulley 34, the feeding rollers of the machine are actuated, as hereinafter described.

To the left of the driving shaft 26 is mounted IOO a shaft 35, which I term an intermediate shaft, and this shaft is journaled in a bearing 36, secured to the framing l0, and in a journal 37 secured to the framing 11, and carries the pulleys 38 and 39, as shown, on opposite sides of the machine, which pulleys 38 and 39 are set in line with the pulleys 32 and 33, for a purpose hereinafter noted. Also mounted on the shaft 26 between the frames 10 and 1I is the large drum pulley 40, from which drum pulley, belts transmit power to the vertical cutters, as hereinafter described. A second table 4l is mounted to the left of the table 12 as shown, on the frames l0 and l1, and extending up from the frame 10 is the slide-way 42, and extending up from the frame l1 is the slideway 43, which slide-ways are adapted to carry the journals 44 and 45 respectively, for the upper surface cutter. The slide-ways are preferably made inclined, as shown, and the journals are fitted to slide up and down on the same by any convenient arrangement or gibbing. Tapped into the rear journal 45 is the screw 46, and tapped into the front journal 44 is the screw 47, and these screws may be turned from the shaft 48, which is journaled in the side frames l0 and Il, as shown, by means of the bevel-gears 49 secured on the screws 46 and 47, and the bevel-pinions 50 secured on the shaft 48, which mesh with the bevel-gears 49. The rod 48 on the outside of the framings, as shown, has a milled head 5I, to which an ordinary crank or wrench can be applied, and by turning the shaft 48, the journals 44 and 45 may be synchronously adjusted up or down, as desired, to adjust the upper surface cutter.

In the journals 44 and 45 is mounted the shaft 52, which carries the cutter 53, which may be of any approved constructiomwhich is-'adapted to smooth off, or finish the upper surface of the beam or plank, as the same is passed through the machine, and this cutter may be vadjusted up and down to nicely take any desired cut by the means before described. On the ends of the shaft 52, are mounted the small pulleys 54 and 55, which may have large anges next to the frame, as shown, and power is transmitted t0 these pulleys from the large pulleys 32 and33 by means of belts 57, which belts 57, on their upper sides, pass directly from the large driving pulleys to the small pulleys on the shaft of the cutter, but which, on their under sides, bear against the belts on the pulleys 38 and 39, for a purpose hereinafter described.

On the journals 44 and 45 are formed lugs 63, to which lugs 63 are pivoted arms 59, and these arms 59 carry a box 60, which I term a weightbox, which weight-box may carry a series of projecting fingers as 62, and a number of dummies as 56, so that the box will be heavily weighted. These projecting fingers 62 are adapted to press on the surface of the beam or plank just before the same reaches the cutter 53, and to hold the same firmly down upon the table 4l, so that the cutter 53 can accurately and nicely work on the material.

Extending around from the boxes 43 and 44, underneath the weightbox 60 is a frame 61 and between this frame 61 and the arms 59, are arranged small adjusting screws 64, by adjusting which, the pressure of the fingers 62 on the material can be regulated. It, also, will be seen that as the boxes 43 and 44, or the cutter 53 is adjusted up and down by the means before described,the entire weight box, its supporting frames, &c., will move with the cutter 53, whereby the relation between the cutter 53 and the fingers 62 always remains the same, and the screws 64 form the adjusting points to vary the relation between the fingers 62 and the cutter 53. Journaled in the side frames I0 and 1I below the cutter 53 is the shaft 58, which is the shaft which transmits powerto the feeding,r mechanism hereinafter described. On the front end of this shaft 58 are arranged the loose pulley 65, and the tight pulley 66, and a belt 67 runs from the small pulley 34 on the main driving shaft 26 to these tight and loose pulleys 65 and 66. This belt 67 is made somewhat slack between the pulley 34 and the tight and loose pulleys 65 and 66,and a belt tightener isused to tighten the belt more or less to somewhat vary the feed. This belt tightener is pivoted on astud 68 secured to the frame l0, and consists of an arm 7l, which has journaled thereon the two rollers 69 and 70, which are arranged on opposite sides of the belt 67, as shown. Extending from this belt-tightener 7l is a rod 72, which has teeth 73 on the same, which teeth 73 are adapted to fit into a catch 75 secured on the frame l0, as shown; and this rod 72 may be moved forward and backward by means of the handle 74 passing to the right of the rod 72. The belt 67 may be thrown from the tight or loose pulley 65 or 66 by means of a belt-shifter 78, which has a rod 77 connected thereto, and a suitable operating handle 76 arranged near the handle 74. Thus, it will be seen that the feed can be thrown off oron, as desired, by throwing the belt 67 from the loose to the tight pulley, and vice versa; and it will also be seen, that the feed can be adjusted by means of the belt tightener, this combination constituting a simple and efficient means for controlling and varying the feed.

On the rear of the shaft 58 is mounted a pinion 79, which meshes with a large gear 80 mounted on a Ysuitable stud projecting from the frame l1; and mounted to turn with the gear 8O is the pinion 81, which meshes with a large gear 82 secured 011 the shaft 89 of the lower left hand feed-roll. This gearing greatly reduces the'speed, and thereby increases the power, so that a powerful feed can be obtained. Also arranged on the shaft 89 of the lower left-hand feed-roll, are gears 83 on both sides of the same, which gears mesh with intermediates 84, and these intermedi- IOO rio

ates 84 mesh with gears 85 of the same size as the gears 83, which gears 85 are secured on the shaft of the right-hand lower feedroll. The intermediates 84 also mesh with the upper intermediates 87 secured on both ends of a shaft 95, and meshing with these upper intermediates on the left-hand side of the same are the gears 86 mountedon the shaft 94; and on the right hand side, are the gears 88, mounted on the shaft 96. On the shaft 89 is arranged a feed-roll 91, which I call the left lower feed-roll; and on the shaft 90 is arranged another feed-roll 92, which I call the lower right feed-roll, and the lower intermediates 84 are arranged on a shaft 93,

which is arranged parallel to the lower feedrolls 91 and 92, and the upper intermediates are arrangedon ashaft 95 parallel to the shaft'93. Mounted on the shaft 94 is .the up per left-hand feed roll 119, and mounted upon the shaft 96 is the upper right-hand feed-roll 120, which feed-rolls are adapted to coact with the lower feed-rolls 91 and 92, to tightly bite the plank or beam to be operated upon, and to feed the same into the machine. By the gearing before described,it will be seen that the feed-rolls turn in a proper direction, so that their opposite peripheries will tend to feed the beam or plank from the right to the left of the machine.

Secured to the frame 10 is the piece 97, which has on the inside thereof suitable vertical guide-ways, as shown in Fig. 1, and secured to the frame 11 is a similar piece 98, which has similar guide-ways. Arranged so as to slide verticaly in these frames 97 and 98 are the sliders 100, tapped into the top of each of the screws 101, which screws 101, pass through suitable lugs in the frames, 97 and 98, and have secured on the top ends thereof, bevel-gears 102, which bevel-gears 102 mesh with bevel-gears A103, secured upon a shaft 104, which is journaled in the frames 97 and 98, and which shaft 104 has a handle 105 on the end thereof. It will be seen, by actuating this handle, that the sliders can be synchronously raised or lowered, as desired, for a purpose hereinafter noted.

Mounted on the shaft 95 to the right of the same, and near the frames 10 and 11, are two swinging-arms 106, which have journals as shown, and in these journals, the shaft 96, which carries the upper right-hand feed-roll 120, is journaled. Also journaled on the shaft 95, to the left thereof are the arms 107, which are also arranged near the frames 10 and 11, and which arms 107 carry journals on the ends thereof, in which journals the shaft 94, which carries the upper left-hand feed-roll 119, is mounted. Thus, it will be seen that the shafts 94 and 96 can be turned around the shaft 95 as a center, and by this means, the shafts 94E and 96 can be adjusted vertitically on arcs around the center of the shaft 95, and that the gears 86 and 88 will always be kept in mesh with the intermediates 87,

no matter how the shafts 94 and 96 are swung. This constitutes a simple and effective means for adjusting the relation between the various feed-rolls, so that any thickness ofimaterial can be passed between the same. Projecting from the sliders 100 to the rightthereof, are the stops 116, against which the arms 106 are adapted to rest, and projecting from the sliders 100 'to the left are the stops 117 against which the arms 107 are adapted to rest. Thus, by adjusting the sliders 100 up or down by the means before described, these stops 116 and 117 will be adjusted up and down, and by this means, the shafts 94 and 96 will be raised and lowered, and the space between the. upper and the lower feed-rolls will be varied.

To keep the. upper feed-rolls nicely against their stops, and on the stop, I pass suitable straps 108 around the arms 107, and similar straps 109 around the arms 106, and I connect the ends of these straps to a .pivoted piece 110, which I .term an equalizer. This equalizer 110 is pivoted on a long arm 111, as shown, which carries at the end thereof a weight 112. The lower ends of the sliders 100 carry suitable guides 121, which lit into guide-ways 122-secured on the inside of the frames, as shown. The sliders 100 also are preferably counter-balanced by means of a weight which is connected to the sliders 100 by means of cords 114, which pass around pulleys 113, secured to the frames 10 and 11.

vThis entire mechanism. constitutes an improved feeding mechanism, and one which is very efficient in operation. The upper feedrolls, it will be noticed, are simply held in their lowered positions by means of the Weights 112; and, if the beam or plank to be operated upon, is very irregular or warped, the uppervfeed-rollers, 119 and 120 will be raised, as the material is drawn in between the same. In other words, the upper feed cylinders are yieldingly held down. Again, it will be seen, that by the means before described, the relation between the upper feedrolls and the lower feed-rolls may be nicely and accurately adjusted, for by adjusting the sliders 100 up or down, the upper feedrolls are adj usted up or down, the stops 116 and 117simply determining the lower limits of the upper feed-rollers, but not at all limiting their upward movement. The equalizer is an important addition to the device, as it Vtends to keep the strain between the two sets of feed-rolls equal. The weights 112 maybe adjusted back and forth on the arms 111, so that any desired degree of tension or pressure between the upper and lower feed-rolls, can be obtained. The arms 111 may have suitable guides as 118 secured to the sliders 100, so that the same will be kept nicely in place. This feeding mechanism constitutes the feeding` mechanism for the whole planing machine, and this feeding mechanism may be applied to any form of planing or matching IOC) IIO

' a similar vertical post 132.

A machine, without departing from the scope of my invention, as expressed in the claims. A guide may, also, be usedbeyond the cutter 5,3, and one convenient Way to arrange this guide is as follows:-The table 41 is slotted as at 157, and tting into this slot is a block 123, which projects up through the slot, and fitting to the block 123 is a guide 124, which is pivoted to the block 123, by means of the screw 126, and which is clamped in place by means of the nut 125, which is tapped on to the head of a bolt projecting up from the block 123, into a slot formed in the guide 124. This block 123 may be moved transversely across the machine by means of a screw 158, which is tapped into this guide-holder123, which screw 158 is mounted in the side fralnes 10 and 11, as shown. The guide 124 may have an extension as 127, and this extension may be slotted, and secured to the guide` 124 by means of screws 128, if so desired. The end of this guide may be held in place by means of a rod or brace 129, which may be adjustably held in a suitable holder 130. It is desirable to have the end of the plank or board which is being operated upon, held down upon the table 41, also the left of the cutter 53, and I have improved the details of' this peculiar holding mechanism, and I vuse the same both beyond the upper cutter 53, and above the lower cutter 207, hereinafter described, and, asl the details and construction o f both these guiding mechanisms are the same, I will describe only one, that to the left of the cutter 53, in detail, the same description being applicable tothe other.

Clamped to the ,side frame 10 is a vertical post 131, and clamped to the sideframe 11 is Fitting on the post 131, is a block 133, which fits nicely to the post 131, and the post 131 has a key-way or slot 134 formed therein, as shown in Fig. 410, andl tapped into the vback of the block 133 is the screw 136, which has an operating han- -dle 135, which screw 136 is adapted to enter the key-way on slot 134 in the rod 131. This key-way on the slot 134 in the rod 131 is tapered in downwardly, and this forms an important point in practice, because, when the block 136 is secured in place, if there is any strong upward pressure on the block 133, the block 133 will not slip; as, if the screw 136 is screwed down tightly to the bottom of the slot 134, it will be impossible to crowd the screw 136 up the incline of the key-way. This forms an important point in the accu'- rate working of the guides or holders. The block 133 has a lug 137 projecting to the side of the same, and tting into this lug is a screw 138, which has a handle 139, and on the under side of this handle 139 are formed teeth or ratchet 140, and engaging these teeth is a latch or pawl 141, which is pressed upward by means of the spring 142 set in the block 133, as shown in Fig. 6, and by this means, the screw 138 maybe moved a slight distance in either direction,.and held by the pawl141.

Fastened on the screw 138 below the lug 137` tapped. A guide-holder 146 is pivoted to thel rod 132, as hereinafter described, and this guide-holder is slotted as at 147, so as to hold the guides, as hereinafter described. The rear side of this guide 146, where the same bears against the block 144, is tapered downwardly, as shown in Fig. 10, and the block 144 is oppositely tapered. Tapped into the block 144 is a screw 149, which has the operating handle 150, and the guide-holder 146 has a groove 151, as shown, which is adapted t0 fit around the` screw 149. The taper .between the block 144 and the guide-holder 146 is so set, that the same will resist upward pressure, the taper preventing the guide-holder from sliding upward on ythe block 144. When itis desired to adjust the guide-holder up or down, the samey can be done by operating the handle 150, as before described.

On the rod 132 is mounteda block 152, and the rod 132 has a slot or key-way 153, cut in the same, into which fits the screw 154, which is tapped in the sliding block 152, and this screw 154 has a suitable operating handle 155. On this screw 154, the guide-holder 146 is pivoted, and the block 152 has a lug 156 so arranged that the guide 146 can be turned around the screw 154 as a pivot, and rest against this lug 156, when it is desired to raise the guide-holder 146 up, so that the guides will be raised clear of the table. When it is desired to turn the guide-holder 146 around in this manner, the screw 149 is loosened so Vthat the tapered portion of the guide-holder IOO 146 can slide up clear of the tapered portion v of the block 144. 'Secured to the guide-holder 146 may be arranged a number of guides or pressure-feet 256, which are adapted to bear upon the beam or plank, and hold the same firmly down against the table.

y In the machine, as shown, there are two upy right or Vertical cutters, which are adapted to operate on both sides ot' the beam or plank, as the same is passed through the machine, and as these vertical cutters are the same in construction, only one will be specifically described. Onc cutter164 is placed in advance of the other cutter 165, and the cutter 164 is adapted to act on the side of the plank nearest the frame 11, and the cutter 165 is adapted to act on the side of the plank nearest the frame 10. These cutters are mounted so as to be transversely adjustable, and so as to be capable of being set on an incline, whereby the side of the plank may be tapered in either direction on either side, as desired. The way these cutters are regulated and arranged, is as follows:-The right-hand rear cutter 164 is mounted on a transverse beam 160, and a IIO to the beam 160 in the same manner.

2c the tapped hole 169.

5 length, it being understood that the left-hand cutteris the samein construction. rllhe beam 160, on the side of the same nearest to the frame, 10,is cutaway inits center so that a sliding carriage 166, having two guide-ways or :o recesses 167 and 168, as shown, can fit into the same. The way this carriage is tted to the beam is shown in Fig. 3 in connection with the left-hand cutter, it being understood, of course, that the right hand cutter is fitted This carriage, or sliding support for the cutter has a tapped hole 169 in the lower part of the same, for a purpose hereinafter described, Aand also, has a plane hole 170, to the right of Fitting into the carriage 166 is a bolt 171, which is tapped into the bearing 175, which bearing 175 forms part of a bearing 175, 176, 177,and 178, 177 being the lower bearing, and 175 being the upper bearing for the up-right cutter shaft 159, and the part 176 being a tie or brace connecting the two bearings 175 and 177; and the shoulder or off-set 178 being a supporting shoulder for the step for the shaft 159. Thus, it will be 3o seen that the whole shaft 159 and its sup.

porting frame canbe swiveled about the bolt .171 as a center. Also, tapped into the framing 175 is a bolt- 172, which is also tapped on its outer end to receive a nut 174, and this bolt 172 passes through a slot 173 formed in the carriage 166, which slot is formed with the bolt 171 as a center so that the shaft 159 and its bearing can be swung about the kingbolt 171 as a center, and the nut 174 can be 4o clamped to securely hold the same in its adjusted position. Fastened on the shaft 159 is the pulley 179, and this pulley is driven from the large drum-pulley on the driving shaft 26 before referred to, by means of the quarter-turned belt 202, as shown in Fig. 3.

rllhe cutter 164 is mounted on the end of the vertical shaft 159, and this cutter may have the usual fluted teeth 180, if so desired, or any otherim proved construction may be used.

5o The end of the shaft 159 is slotted as at 181,

and fitting into the slot is a screw 182, which is tapped into the cutter 164, whereby the cutter will be held from turning on the shaft 159. The head 164 may be adjusted vertically on the end of theshaft 159 by means of the screw 183, which is tapped into the end of the head, as shown, and which screw may have a check-nut 184 on the end of the same. Bolted to the lower part of the framing 177 6o which carries the vertical shaft 159, is the lower carriage 185, which has a projecting arm 186, and which carriage or support is secured to the framing 177 by means of bolts 187. The arm 186 is adapted to fit on to the guide 163, which is bolted between the frames l 10 and 1l., as shown in Fig 2 so as to support the lower end of the framing and shaft,

and this guide 186 may be clamped tightly in place on the beam 163 by meansof the screw 188, if so desired. Tapped in the lower projecting arm 178 of the shaft supporting frame is the step-screw 189, which may have a suitable check-nut 190 on the same, and the lower part of the shaft-supporting frame is slotted, as shown, as at 191, and fitting into this slot is the screw 192, which is tapped into the step 193, as shown, whereby, by loosening the screw 192, and actuating the screw 189, the step may be adjusted in relation tothe shaft. The step 193 has a suitable cover as 194, which may be lifted up for the purpose of putting oil into the step, andthe step is grooved as at 195 to form an oil passage extending beyond the center of the shaft 159, as shown, and this groove 195 connects by an oil passage 196 to the top of the step, whereby there will be lefta framing as 197 completely around the lower end of the shaft. y

It will be noted that the lower end of the shaft 159 is tapered where the same fits into the step, and this construction of the step is useful, in that the oil put into the step will work up through the framing, yand .will then fall to the bottom of the step through the groove 196 down to the lower oil chamber 195, so'that the oil will be working at all times around the bearing of. the shaft, whereby a very easy and nice bearing is provided for the lower end of the shaft.

It will be seen that the end shaft cutter and framing may be moved transversely in either direction upon the beams 160 and 163, and I preferably use a screw 198 for moving the upper carriage 166 along the beam 160; this screw 198 being tapped into the hole 169 in the carriage 166,before referred to. When it is desired to move the cutter transversely, the bolt 188 is loosened, and the screw 198 is actuated, when the whole framing will be moved along the two beams 160 and 163, and when the cutter is in its desired position, the same may be rigidly secured by tightening the bolt 188. When it is desired to set the cutter on an incline, the same can be readily done by loosening the screw 188 and the nut 174, and swinging the cutter to the desired inclined position, whenthe nut 174 and the screw 188 will be tightened to hold the cutter in the adjusted inclined position. The limit of the incline which may be given to the cutter is the arc that the screw 188 may be moved, and still be in position to engage the beam 163, and by varying the proportion of the parts, any desired incline may be given to the cutter, the belt 202 simply following the pulley 179, no matter in what position the same is set.

lt is desired in most cases to hold the cutter so that the same cannot slip transversely, and affect the cut of the same, and to provide against this Iuse y following means: Arod IOO IIO

fits in the hole 170 of the carriage 166 before referred to. This rod 199 is in cross section a pinion; orin other words, is iiuted substantially its entire length, and tapped on the screw 198 isa check-nut 200, which is adapted to bear against the side of the carriage 166, as shown in Fig. 7; and on which check-nut 200, is a gear which meshes with the teeth on the rod 199. By turning the rod 199, it will be seen that the check-nut 200 may be moved forward and backward on the screw 198. Also, it will be seen that if the check-nut 200 is moved slightly away from the carriage 166 and the screw 198 revolved the nut 200 is moved in unison with the carriage 166, as the nut 200 will be held from turning by means of the rod 199, which is then stationary, so that all there is ever necessary to turn the rod 199 is simply to loosen and tighten the check-nut 200 against the carriage 166. This forms a very simple and efficient means for tightly clamping the carriage in whatever position the same is set. Then it is desired to adjust the cutter, the check-nut is simply given a slight turn, the screw 198 turned to adjust the cutter, and then the check-nut 200 turned back, to tightly clamp the carriage in its adjusted position. A suitable handle 201 may be arranged on the end of the rod 199, as shown, whereby the same can be actuated, and the ends of the screw 198 may be milled, so that the screw can be readily actuated. It will be seen by reference to Fig. 2 that the handle 201 is so arranged, that when the check-nut 200 is clamped against the carriage the handle 201 will be over the end of the screw 198. The aim of this construction is as follows:-If the screw 198 should be turned when the check-nut 200 was tightly against the carriage, it might tend to strip or injure the threads of the screw; but, with this construction, it is always necessary to turn the handle 201, so that the check-nut will be loosened before the end of the screw 198 can be got at. This'forms an important and neat point in practice. A vertical cutter arranged in this manner forms a very strong, simple, and accurate device, and one which may be used with great advantage in machinery of the class described. n

As the mounting ofthe nut of the left-hand cutter 165 is the same as that of the righthand cutter 164, the same will not be described at length. v Behind the vertical cutters 164 and 165, I preferably arrange the under cutter. This cutter 207 may be mounted upon a suitable shaft 206, which shaft 206 is journaled in boxes 208 and 209, which are vertically adjustable on the frames 10 and 11. These boxes 208 and 209 are connected or tied together by a suitable framing 260, as shown, which forms a shaving chute, which is adapted to throw the shavings from t-he cu ter 207 to the left, as shown in Fig. 3. Al by this construction, it will be seen that the journal-boxes are rigidly secured together, and this insures the nice running of the shaft, as the boxes would not have any independent vibration. The same point is also true of the boxes of the upper cutter 53, which are tied together by the framing 61, before referred to. Tapped into these boxes may be the vertical adjusting screws 213, which are mounted in suitable bearings secured to the frames 10 and 11, as shown in Fig. 3, and on the ends of these screws, may be arranged bevelgears 211, which mesh with bevel-pinions 212, secured upon a rod 210, which is journaledv in the frames 10 and 11, as shown, whereby, by turning this rod 210, the cutter 207 may be raised or lowered and adjusted accurately. The ends of the rod 210 are milled off as shown in Fig. 2 so that a wrench can be readily applied to the ends of the same for the purpose of adjusting the cutter 207 vertically. On the cutter shaft 206 are mounted the pulleys 204 and 205, and suitable belts 203 run between the pulleys 204 and 39 and the pulleys 205 and 38. Thesebelts 203 are driven from the belts 57 by frictional contact, the belts 57 passing up over a portion of the surface of the belts 203 on the intermediate pulleys, as shown in Fig. 2, and by this means, the under surface cutter is driven without .any complication of belts.

A suitable guiding mechanism may' be provided between the table 41 in connection with the vertical cutters before described, and one convenient arrangement of the same is to mount a small guide 216 to the inside of the cutter 164, this small guide or tableV 216 being secured to the top of the right-hand carriage 166, and a similar table or guide 215 may be used in connection with the left-hand cutter 165, and may be secured to the top of the left-hand carriage 166. Beyond these guides 216 and 215, I preferably arrange another guide 214, which is secured to the side frames 10 and 11, by means of screws 230, which fit into slots 229 on said guide 214, whereby this guide 214 maybe adjusted in relation to the lower cutter 207.' This guide or table 214 may have a slot 217 formed in the same, and a side-guide 218 may be laid on the table 214, and the table 227, hereinafter described, and this side-guide is held in place transversely by means of the bolt 219, which fits in the slot 217 of the table 214.

On the end of the side-frame 10 is hinged the swinging end or framing 221, which has the hinge 228 fitting to the-side-frame 10, as shown, whereby, all the framing beyond the lower cutter may be swung out to one side so that the' lower cutter 207 can be readily got at. On the other side of this swinging frame 221 is formed a lug 250, which is adapted to come in line witlrthe lug 251 on the frame 1l, when the supporting table 221 is in position or closed, and a tapered pinion 252 is adapted to be tapped into these lugs IDO IlO

so as to securely lock the table in its closed position.. Fitting into the swinging framing 1s an adjustable framing 222, which may be adjusted up and down by means of screws s 223 tapped into ears on the table 222, which screws are tted into lugs on the framing 221',

A and which screws have on the ends thereof,

, to, may be clamped to the edge of this table 227, by means of a bolt 220, which engages a lug 22S fitting upon the end of the table 227. This table 227 may be adjusted on the vertically adjustable table 222 in relation to the cutter 207, as the same is held to the vertically sliding table 222 by means of screws 232, which are tapped into the table 222 through slots 231 cutinto the table 227. The idea of making all the surface beyond the lower cutter 207 vertically adjustable, is so that the beam or plank will be nicely held beyondthecutter,the cutter changingthe height of the under surface of the plank. As before stated, all the framing beyond the lower cutter 207 may be swung out so that the lower cutter can be inspected and sharpened.

The details hereinafter claimed are applicable to any form of planing or matching machine, and where I have shown a machine organized to embrace all my improved details, it will bevseen that the same are capable of independent use.

The details and arrangement of parts herein shown and described, may be greatly varied by a skilled mechanic withoutdeparting from the scope of myinvention, as expressed in the claims.
